Semantic Coherence — The Lens
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Semantic Coherence
Homepage promise vs. Sub-page reality.

There is no detectable semantic drift between the homepage signal and sub-page substance. The homepage promise of ‘Active Alerts’ and ‘Forecast Maps’ is directly fulfilled by high-resolution surface analysis and hazard-specific information blocks. The transition from national-level data on the homepage to local safety procedures for hazards like ‘Rip Currents’ or ‘Tornadoes’ is perfectly aligned. Every navigation element leads to a page that provides exactly the depth of information promised by the link label.
Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
